So like a lot of people i was going to try and go for Manchurian candidate achievement and thought to myself: if i pick Korchin who are Buddhist, i can get the Land of Eastern Jade achievement in the same run. so i went in to the the EU4 files and looked for the Manchurian Candidate achievement and it said that korchin was one of the tags that could get the achievement, so i assumed that they could get it. So i played as korchin for some time and conquered most of Manchuria and thought that if i changed culture to Manchu (Korchin starts as some mongol culture) the decision to form Manchu would appear but no, so now my question is: is it possible for korchin to form Manchu, or Qing for that matter? Because if not, their tag should not be listed as one of the ones that can achieve the achievement!
